LookUpEdit.GetSelectedDataRow() Method

Returns a data source row corresponding to the currently selected edit value.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v24.2.dll

Declaration

C#

public override object GetSelectedDataRow()

VB.NET

Public Overrides Function GetSelectedDataRow As Object

Returns

Type	Description
Object	An object that represents a data source row corresponding to the currently selected edit value.

Remarks

The currently selected value is specified by the editor’s EditValue property. The GetSelectedDataRow method returns the data source row that contains this edit value in the key field, specified by the RepositoryItemLookUpEditBase.ValueMember property.

To get access to other data source rows by their key field values, use the RepositoryItemLookUpEdit.GetDataSourceRowByKeyValue method.

Example

In the following example, a LookUpEdit control is bound to the Categories table, which contains the CategoryID, CategoryName, Description and Picture fields. The control displays data from the first three fields. When you select a new record in the LookUpEditor (the control’s BaseEdit.EditValueChanged event), a separate PictureEdit control displays this record’s Picture field value.

C#

private void simpleButton1_Click(object sender, EventArgs e) {
    // Select a record in the LookUpEdit control
    lookUpEdit1.EditValue = lookUpEdit1.Properties.GetKeyValueByDisplayValue("Condiments");
}

private void lookUpEdit1_EditValueChanged(object sender, EventArgs e) {
    LookUpEdit lookUp = sender as LookUpEdit;
    // Access the currently selected data row
    DataRowView dataRow = lookUp.GetSelectedDataRow() as DataRowView;
    // Assign the row's Picture field value to the PictureEdit control
    if (dataRow != null) {
        ImageConverter imConverter = new ImageConverter();
        pictureEdit1.Image = (Bitmap)imConverter.ConvertFrom(dataRow["Picture"]);
    }
}

VB.NET

Private Sub SimpleButton1_Click(sender As Object, e As EventArgs) Handles SimpleButton1.Click
    ' Select a record in the LookUpEdit control
    LookUpEdit1.EditValue = LookUpEdit1.Properties.GetKeyValueByDisplayValue("Condiments")

End Sub

Private Sub LookUpEdit1_EditValueChanged(sender As Object, e As EventArgs) Handles LookUpEdit1.EditValueChanged
    Dim Lookup As LookUpEdit = CType(sender, LookUpEdit)
    ' Access the currently selected data row
    Dim DataRow As DataRowView = CType(Lookup.GetSelectedDataRow(), DataRowView)
    ' Assign the row's Picture field value to the PictureEdit control
    If Not DataRow Is Nothing Then
        Dim imConverter As ImageConverter = New ImageConverter()
        PictureEdit1.Image = CType(imConverter.ConvertFrom(DataRow("Picture")), Bitmap)
    End If
End Sub
